Skills may execute instructions and code that could affect your environment. Marketplace scans reduce risk but do not guarantee safety. Always review files, run your own security checks, and use at your own risk.

I understand these skills can contain unsafe or unintended behavior, and I will review and security-scan before use. No warranty, suitability, or outcome is guaranteed.

# /cs:post-mortem — Honest Retrospective

**Command:** `/cs:post-mortem <decision-path>`

Closes the strategic sprint loop. Scores a decision against pre-committed success and kill criteria, and revisits preserved dissent.

**Pipeline:** /cs:office-hours → /cs:brief → /cs:boardroom → /cs:decide → /cs:execute → /cs:post-mortem

## When to Run

- At the 90-day checkpoint
- When a kill criterion triggers
- After a major decision is reversed
- Quarterly on all decisions of the past quarter

## Inputs

- The decision record
- The execution plan
- Actual outcomes (metrics, events, customer signals)

## Output: Post-Mortem Record

Saved to `~/.claude/postmortems/YYYY-MM-DD-<slug>.md`:

```markdown
# Post-Mortem: <decision title>
**Decision date:** YYYY-MM-DD
**Post-mortem date:** YYYY-MM-DD
**Status:** WIN / PARTIAL / LOSS / MIXED

## Outcome Scoring (against pre-committed criteria)

| Success Criterion | Threshold | Actual | Met? |
|---|---|---|---|
| <metric 1> | <threshold> | <actual> | ✅ / ❌ |

| Kill Criterion | Threshold | Actual | Triggered? |
|---|---|---|---|
| <metric> | <threshold> | <actual> | ✅ / ❌ |

**Overall:** WIN / PARTIAL / LOSS / MIXED

## What We Got Right
- <factor 1>
- <factor 2>

## What We Got Wrong
- <factor 1>
- <factor 2>

## Preserved Dissent
[Revisited with outcome scoring]

## Assumption Audit
[Original brief's assumptions scored]

## Process Lessons
- Phase 2 isolation worked?
- Devil's advocate concerns?
- Cadence was right?

## Forward Actions
- [ ] <change to operating system>
- [ ] <new decision based on learning>
```

## Why Pre-Committed Criteria Matter

Eliminates retroactive justification. The numbers either matched or they didn't.

## Routing

- `/cs:brief` — if post-mortem surfaces a new decision
- `/cs:freeze` — if post-mortem reveals a process gap
- Update company-context.md via `/cs:onboard`
